我在前端使用angular，在后端使用sails&postgresql。我得到tcp连接错误和代码42703错误。有人能提出他们对那件事的看法吗。datastore.js文件内容如下：

module.exports.datastores = {

  /***************************************************************************
  *                                                                          *
  * Your app's default datastore.                                            *
  *                                                                          *
  * Sails apps read and write to local disk by default, using a built-in     *
  * database adapter called `sails-disk`.  This feature is purely for        *
  * convenience during development; since `sails-disk` is not designed for   *
  * use in a production environment.                                         *
  *                                                                          *
  * To use a different db _in development_, follow the directions below.     *
  * Otherwise, just leave the default datastore as-is, with no `adapter`.    *
  *                                                                          *
  * (For production configuration, see `config/env/production.js`.)          *
  *                                                                          *

  default: {

    /***************************************************************************

    * Want to use a different database during development?                     *
    *                                                                          *
    * 1. Choose an adapter:                                                    *
    *    https://sailsjs.com/plugins/databases                                 *

    * 2. Install it as a dependency of your Sails app.                         *
    *    (For example:  npm install sails-mysql --save)                        *
    *                                                                          *
    * 3. Then pass it in, along with a connection URL.                         *
    *    (See https://sailsjs.com/config/datastores for help.)                 *
    *                                                                          *
